Primary | Change From Baseline in DAS28 Score at Week 24 | DAS28 calculated from the swollen joint count (SJC) and tender joint count (PJC) using the 28 joints count, the erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hour]) and Patient Global Asessment of disease activity (participant- rated arthritis activity assessment) with transformed scores ranging 0 to 10; higher scores indicated greater affectation due to disease activity). A clinically meaningful improvement in DAS28 was defined as an improvement of 1.2 units. | Week 24 | No |
Secondary | DAS28 Score by Treatment Course and Follow-up (FU) Visit | DAS28 was assessed during follow-up at the specified timepoints following each course of treatment (participants could have received up to 3 courses of treatment with rituximab). The DAS28 consists of SJC and TJC measurements, the ESR (measured in mm/hr), and Patient Global Asessment of disease activity (participant-rated arthritis activity assessment) with transformed scores ranging 0 to 10; higher scores indicated greater affectation due to disease activity. DAS28 less than or equal to (=)3.2 equals (=) low disease activity, DAS28 >3.2 to 5.1 = moderate to high disease activity. | Screening, FU Weeks 8, 16, and 24, and FU Months 9 and 12 | No |
Secondary | Percentage of Participants With European League Against Rheumatism (EULAR) Response of 'Good' or 'Moderate' by Treatment Course | DAS28 was assessed during follow-up at the specified timepoints following each course of treatment (participants could have received up to 3 courses of treatment with rituximab). The DAS28-based EULAR response criteria were used to measure individual response as none, good, and moderate, depending on the extent of change from baseline and the level of disease activity reached. Good responders had a change from baseline >1.2 with a DAS28 score =3.2; moderate responders had a change from baseline >1.2 with a DAS28 score >3.2 to =5.1 or a change from baseline >0.6 to =1.2 with a DAS28 score =5.1. | Week 24 | No |
Secondary | Percentage of Participants Achieving a Response By EULAR Category and Treatment Course | Response was assessed during follow-up at the specified timepoints following each course of treatment (participants could have received up to 3 courses of treatment with rituximab). The DAS28-based EULAR response criteria were used to measure individual response as none, good, and moderate, depending on the extent of change from baseline and the level of disease activity reached. Good responders had a change from baseline >1.2 with a DAS28 score =3.2; moderate responders had a change from baseline >1.2 with a DAS28 score >3.2 to =5.1 or a change from baseline >0.6 to =1.2 with a DAS28 score =5.1; non-responders had a change from baseline =0.6 or change from baseline >0.6 and =1.2 with a DAS28 score > 5.1. | Week 24 | No |
Secondary | Health Assessment Questionnaire - Disability Index (HAQ-DI) Score by Treatment Course | HAQ-DI was assessed during follow-up at the specified timepoints following each course of treatment (participants could have received up to 3 courses of treatment with rituximab). The HAQ-DI score consists of questions referring to 8 categories: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and common daily activities. For each of the categories, participants reported the amount of difficulty they had in performing 2 or 3 specific sub-category items. Each item scored on 4-point scale from 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. The standard disability score was calculated from the 8 categories by dividing the sum of the individual categories by the number of categories answered ;total possible score range 0-3 where 0 = least difficulty and 3 = extreme difficulty. The questionnaire was provided in a German translation and was scored based on the instructions from the Stanford University Medical Center. | Screening, FU Weeks 8, 16, and 24, and FU Months 9 and 12 | No |
Secondary | Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) Score by Treatment Course | FACIT-F was assessed during follow-up at the specified timepoints following each course of treatment (participants could have received up to 3 courses of treatment with rituximab). The FACIT fatigue scale is based on a 13-item questionnaire to assess the therapy-induced fatigue. Participants scored each item on a 5-point scale: 0 (not at all) to 4 (very much). Larger the participant's response to the questions (with the exception of 2 negatively stated), greater was the participant's fatigue. For all questions, except for the 2 negatively stated ones, the code was reversed and a new score was calculated as (4 minus the participant's response). The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (best) to 52 (worst). The assessment was originally developed for chronic illnesses and is now validated for patients with rheumatoid arthritis (RA). The questionnaire was provided in a German translation. | Screening, FU Weeks 8, 16, and 24, and FU Months 9 and 12 | No |
Secondary | Short-Form 36 (SF-36) Physical Composite Scores (PCS) by Treatment Course | SF-36 was assessed during follow-up at the specified timepoints following each course of treatment (participants could have received up to 3 courses of treatment with rituximab).
